Enhanced Toluene Adsorption in aqueous solution by employing modified Coconut based Activated Carbon

The aim of this research is to produce high quality coconut shell based activated carbon, and
testing the adsorption capabilities of Toluene in aqueous solution on modified coconut based
activated carbon.
One of the most proven effective way for organic solvent removal is adsorption by using
activated carbon, using coconut shell as a raw material for the activated carbon due to its
availability in Malaysia, and its high recommendation as a raw material worldwide, After
sometime during adsorption, the activated carbon will be saturated and need to be regenerated,
which is expensive. By increasing the adsorption capacity of the activated carbon, the frequency
of regeneration can be reduced, therefor reducing the operating cost. The adsorption capacity
can be increased by modifying the surface of the activated carbon. Method of modification will
be decided depending on the targeted impurities. Based on the characterization analysis, the
morphologies of the activated carbon has changed.
The experiment would be conducted on a packed bed of activated carbon, and tested at certain
values of mass flow rate, pressure and temperature. One of the most common methods used for
VOC (Volatile Organic compounds) removal is by using activated carbon. This Experiment
would be firstly producing activated carbon and testing it activity level, and then experimenting
of the effect and the efficiency of using that activated carbon in toluene purification.
The Main aim of this study is to prove the efficiency and the effectiveness of using coconut
shell based activated carbon in the purification ofVOCs (Toluene).
